Eli5: how do people hear musical notes?

718 views

I have no musical knowledge so bear with me.

How can people hear a note played or a word sung and this to themselves “oh that’s an A flat” or something along those lines. Or how can they identify that they are not singing the right note and know how to modify it to get to the correct one?

What about tuning instruments. How can someone do that by ear and just know that it’s in tune?

The mind boggles!

Instruments will be tuned to a standard- in an orchestra, a single oboe typically gives a pitch which serves as a reference for everyone else. For a singer with a guitar, the reference might be one of the strings on the guitar to which the other strings are tuned if the guitarist doesn’t have a tuner.

Another commenter mentioned perfect pitch; the trained version of that is relative pitch, which means that *given a reference pitch* a person can identify another pitch.
